IMPROVEMENT IN TRUSSES.

Specification forming part of Letters Patent N 0. 222,579, datedDecember 16, 1879; application filed October 331, 1879.

To all whom it may concern:

Be it known that I, GEORGE W. ELLIS, of the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new andImproved Truss and I do hereby declare that the following is a full,clear, and exact description of the same. r

My invention is an improvement in the class of trusses for reducinghernia, in which the pad is attached to a slotted bar whose head is heldin a clamp that allows adjustment of the pad in various positions.

My invention consists in constructingthe bar to which the pad isattached with a ball for adjustment at its upper end and with an openslot, forming two parallel prongs, which enables the pad to be attachedor detached with great facility.

This construction of the barO with an open slot or parallel prongsenables the pad A to be readily detached from the bar and anothersubstituted, which is particularly'important in fitting trusses, sinceit often happens that the pad attached to a truss is uncomfortable orotherwiseunsuitable to the wearer, and in such The pad A is attached tothe spring B by means of a sliding or adjustable bar, G, having an openslot, a, in one end, and a ball or spherical protuberance, b, on theother, which is secured in a clamp, D.

The details of construction, arrangement, and operation of said partsare as follows: The pad A is provided with a fixed T-shaped stud, c, anda detachable clamp-screw, d. The slotted bar 0 is secured to the pad Aby slidin g its parallel prongs under the flanges of the stud c and thehead of clamp-screw d, which latter is then tightly screwed down on thebar to hold it firmly.

The clamp D consists of the recessed plate 0, which is fixedly attachedto the spring of the truss and a movable or detachable plate, f, whichis adapted to partly embrace the ball 0, and is provided with teeth toenable it to hold the pronged bar 0 immovable in any position. Saidplate f is secured by a clampscrew, g.

What I claim is In a truss, the bar constructed with an open slot orparallel prongs and a spherical head integral therewith, as shown anddescribed, to adapt it to use with a pad and with the clamp of thebody-band, as specified.
